THE ASSAY OF COMPOSITION AND PHYSICOCHEMICAL CHARACTERISTICS OF ANTIBACTERIAL MATTERS FROM HOUSEFLY LARVAE
家蝇幼虫抗菌物质组成及其理化性质

Using the methods of plate growth inhibition assay and acid /basic polyacry-lamide gel alactro phoresis, the composition and physicochemical charact eristics of antibacterial matters from housefly (Musca domestica) were studied. The results showed that the antibacterial matters from housefly were basic and neutral proteins consisting of five components. They have stable physicochemical properties such as heat stability, resistance to treatment with high ion con centration, relatively extreme pH solution, living in room temperature for 6h, freezing and thawing for 12 times.
